Ideal when you need a single carrier for multi-pet outings or larger pets that don’t fit standard carriers. Swivel wheel trolley box — Detachable universal wheels rotate freely for smooth, low-effort rolling. Convert between handheld carrier and wheeled trolley in seconds. Breathable and comfortable — Mesh panels on multiple sides promote airflow and let your pet see out, helping them stay comfortable and less anxious during transit.
